“…Cattle CH 4 emission represents energy loss of around 6% in grazing animals and 3.5% in confined animals (IPCC, 2006). According to the presented results, we can infer that the inclusion of concentrate supplement in grazing animals can reduce energy losses, resulting in an efficiency of energy utilization similar to those observed in confined animals (Fiorentini et al, 2014), corroborating Neto et al (2015). In the evaluation of energy loss in cattle fed only grass, Kurihara et al (1999) found a 10.9% energy loss and Pelve et al (2012) observed that CH 4 emissions from nonlactating cows and heifers fed forage harvested from seminatural heterogeneous forages correspond to an average of 8.9% of gross energy intake.…”

“…The CH 4 emission was of approximately 10 g per kilogram of DMI in the diet without additional fat, a lower value than that observed in most studies with beef cattle using the SF 6 tracer technique. Neto et al (2015) showed emission values of 15.8 g/kg DMI in Nellore bull in pasture fed supplements containing high or low starch with or without soybean grain. These values are far higher than those found in this study.…”

“…Many products with different fatty acid profiles can be used as fat sources in diets for ruminants (Fiorentini et al, 2014;Neto et al, 2015). However, there are few studies that assess the effect of lipids upon CH 4 emission mitigation and upon performance of zebu cattle grazing tropical pasture.…”

-The objective of this study was to evaluate the effect of lipid sources on voluntary intake, digestibility, performance, and CH 4 emission of Nellore steers grazing Brachiaria brizantha cv. Xaraés forage in the dry season. Forty-five Nellore steers with average weight of 442±34 kg were alloted into one of the five treatments: without additional fat; with palm oil; with linseed oil; with protected fat; and with whole soybeans. The supplements were provided daily and quantities were adjusted to 1% of body weight and diets were formulated in accordance with the Cornell Net Carbohydrate and Protein System. The experimental design was completely randomized with five treatments and two replications. There were no effects on dry matter, organic matter, and neutral detergent fiber intake with the inclusion of lipids in the diet. The neutral detergent fiber showed decreased digestibility in animals receiving linseed oil and palm oil treatments compared with animals receiving the diet without additional fat. The linseed oil treatment reduced CH 4 emissions by 38% when expressed in mg/d/kg BW and tended to reduce the emission in g/d/kg BW 0.75 . Lipid sources did not affect the weight gain of the animals. The intake and performance of grazing Nellore steers supplemented at 1% body weight with lipid sources were not modified. However, fiber digestibility was reduced with palm or linseed oil addition. Linseed oil reduced enteric CH 4 emissions. Linseed oil has the potential to reduce enteric CH 4 emissions in continuous tropical grazing systems based on B. brizantha grass.

Four Holstein steers with ruminal and duodenal cannulas were used in a 4 × 4 Latin square design to examine the effect of daily intake of 0, 2, 4 or 6 g/steer of standardized plant extract containing a mixture of quaternary benzophenanthridine alkaloids and protopine alkaloids (QBA+PA) on the characteristics of ruminal fermentation and characteristics of digestion. The basal diet consisted of a steam-flaked corn-based finishing diet that contained 62% corn and 12% sudangrass hay and the rest of diet was composed of mainly dried distillers grains, molasses, fat, and minerals. The source of QBA+PA used was Sangrovit-RS (Phytobiotics Futterzusatzstoffe GmbH, Eltville, Germany) and supplementation levels of 2, 4, and 6 g Sangrovit-RS∙steer∙d, which represented a net daily ingestion of approximately 6, 12, and 18 mg of QBA+PA compounds, respectively. Inclusion of QBA+PA linearly increased ( = 0.04) flow to the duodenum of nonammonia N and linearly decreased ( < 0.01) duodenal flows of ammonia N. Ruminal microbial efficiency (duodenal microbial N; g/kg OM fermented in the rumen) and protein efficiency (duodenal nonammonia N; g/g N intake) were increased ( < 0.05) as the level of QBA+PA increased. There were no effects of QBA+PA supplementation on ruminal, postruminal, and total tract digestion of OM, starch, and NDF, but postruminal and total tract digestion of N increased ( < 0.01) as the level of QBA+PA increased. Digestible energy of the diet tended to increase (linear affect, = 0.09) with QBA+PA supplementation. Ruminal pH and total VFA molar concentrations were not different between treatments. Ruminal NH-N concentration linearly decreased ( = 0.02) with QBA+PA supplementation. Ruminal molar proportion of acetate increased ( = 0.04) as the supplementation level of QBA+PA increased. It is concluded that QBA+PA supplementation enhances efficiency of N utilization in feedlot steers fed a steam-flaked corn-based finishing diet. This effect was due, in part, to enhanced ruminal microbial efficiency, decreased ruminal degradation of dietary nonammonia N, and enhanced postruminal N digestion.

“…Few studies (Neto et al, 2015) to date have investigated the combined effect of starch and lipids on animal performance and methane emission. We hypothesized that replacing corn with soybean hulls as an energy source, combined with ground soybean as a lipid source, may reduce methane emissions without affecting the performance or carcass characteristics of feedlot beef cattle.…”

It was hypothesized that replacement of corn with soybean hulls as the energy source, combined with ground soybean as the lipid source, would reduce methane emissions from feedlot animals without affecting their performance. This study aimed to evaluate the effects of including ground soybean combined with either a high or a low level of starch on intake, digestibility, performance, and methane emission of young Nellore bulls (n = 28, initial weight = 395 ± 32 kg) in the feedlot during the finishing phase. Diet treatments consisted of high (HS; approx. 250 g/kg) or low (LS; approx. 110 g/kg) starch levels, with (WSB) or without (NSB) soybean. Ground soybean was added as a lipid source to diets HS-WSB, LS-WSB, HS-NSB, and LS-NSB, representing 58.7, 64.6, 24.8, and 31.4 g/kg ether extract in the total dry matter, respectively. Animals were distributed in a completely randomized design, in a 2 × 2 factorial arrangement. After 119 days, the animals were slaughtered. Animals fed soybean demonstrated an average reduction of 11% in their intakes of dry matter, organic matter, and crude protein (P = 0.01). There was a significant effect of the association between starch and soybean on neutral detergent fiber intake (P = 0.01). Diets containing soybean affected the digestibility of the animals, reducing the apparent digestibility of dry matter by 3% (P = 0.02) and the digestibility of organic matter by 2.8% (P = 0.03). A significant interaction was detected between starch and soybean on the apparent digestibility of ether extract (P = 0.02) and neutral detergent fiber (P = 0.04); the lowest values for ether extract (750 g/kg) and neutral detergent fiber (432 g/kg) were obtained with HS-WSB. The animals that received WSB had their feed efficiency increased by 17% (P = 0.01). The enteric CH 4 emissions of the animals fed WSB reduced significantly (P = 0.01), with 28% decrease in g CH 4 /d and g CH 4 /y, 16% decrease in g CH 4 per kg of dry matter intake, and 23% decrease in CH 4 losses per percent of gross energy intake. The inclusion of approximately 250 g/kg of soybean in the diet of young Nellore bulls in the feedlot provides an increase in their feed efficiency and reduces their enteric methane emission, regardless of the level of starch in the concentrate.
